ROBERT R. OOFFEY, OF STURGEON, MISSOURI.

CHURN.

SPECIFICATIGN forming part of Letters Patent No. 267,496, dated November 14, 1882.

Application led August 7, 1882. (No model.)

' exact description of the invention, which will enable others skilled in the artto which it appertains to make and use the same, reference bemg had to the accompanying drawings,

- which form a part of this speciiication, and in which- Figure 1 is a vertical sectional view of my improved churn. Fig. 2 is a perspective view ofthe flasher-staff with its dashers. Fig. 3 is a side View of the frame which supports the dasher-staff, the dashers, and the gearing for operating it.

Similar letters of reference indicate corresponding parts in all the figures.

My invention has relation to churns with rotary dashers; and it consists in an improved construction of the churn-body or cream-receptacle andA its cover, whereby I provide means for aerating the contents of the churn, substantially as hereinafter more fully described and claimed.

In the accompanying drawings, the letter A represents the churn-body, which may be of wood, stoneware, metal, or other material, made with a tapering or cone-shaped body, and having an outside hoop or shoulder, c, which forms a support for the frame that carries the dashers and their gearing. Said frame consists of two side pieces, B B, connected at the top by a cross-piece, G, and at their lower ends by a anged cover, D, and below this by a collar, E, so that when the frame with its cover is superimposed upon the churn the collar E will rest upon the annular shoulder c upon the outside of the churn, as clearly shown in Fig. 1 of the drawings.

The gearing for operating the dasher consists of a beveled wheel, F, which gears with pinions G and H, one of which is keyed upon a shaft, g, which passes throughy the tubular shaft h of pinion H. At the lower end of shaft f/ is secured the bottom dasher, l, which has vertical blades z', and is bent at the lower end of its i'our arms to form Haring wings h. rlhe top dasher, K, is of similar construction-that is, it consists of four blades crossing each other at right angles, and provided with downward depending blades 7c, which, in operating the dasher, work in the open spaces formed between the blades t' z' of the lower dasher. The top dasher, K, is fastened upon vthe tubular shaft 7L, its innermost blades, k', passing down along the tubular shaft to its bottom, and being soldered or otherwise rmly secured thereto at right angles to one another. The lower end ofthe central or inner shaft,g, forms a step or pinion,which works in a gudgeon in the center of the churn-bottom.

If desired, and to facilitate the operation of the churn, the lower ends of the depending blades k of the upper rotary dasher, K, may be bent a little in a direction opposite to that of the flaring wings 7L of the lower rotary dasher, H, as shown at k2, so as to more readily intercept and diverge the current of the cream thrown up from the bottom of the churn by the aring wings h.

By supporting the frame which carries the dashers and their .gearing upon the annular ring or shoulder a upon the outside ofthe churn-body instead of upon the cover, a small air-s pace (designated by d) is left between the cover and the body of the churn for the purpose of aerating the contents of the same, the air entering space d through the annular slot or openin g e, form ed between the tlan ged cover D and the supporting-ring E. K

My improved churn causes the butter to come rapidly, and as the dashers and other operating mechanism are secured upon the frame B B O, which in turn is supported upon the cover D and ring` E, these may be readily removed from the churn-body when it is de sired to remove the butter; nor do I require pipes or air-ducts for aerating the contents ot' the churn, which are objectionable, inasmuch as they are apt to be clogged up with the cheese or butter formed during the operation of churning.

Having thus described my invention,l claim and desire tosecure by Letters Patent oi' the United States- In a churn of the described class, the combination of a tapering churn-body or creamreceptacle, A,n1ovided with an exterior annu- In testimony that I claim the foregoing as hn* flange o1 shoulder, a, and a anged cover, my own I have hereunto afxed my slgnatnre 1o D, connected to its supporting-ring E hy the in presence of two witnesses.
